    Abstract Background: The utility, diagnostic yield and accuracy of lung biopsies in pediatric oncology patients are variable. Here we describe our preliminary results using intraoperative electromagnetic navigation bronchoscopy (IENB) for peripheral lung lesions to increase the surgical yield and accuracy in pediatric oncology patients.
    Methods: From May 2018 until October 2020 all surgical lung biopsies on pediatric oncology patients were performed using IENB technology. IENB and tattooing with methylene blue dye, Indocyanine green dye or both followed by Video-assisted Thoracoscopic Surgery (VATS) was performed in the same setting. Data were collected retrospectively. Data points included diagnosis, technical success, pathologic diagnosis and alteration in treatment management and complications.
    Results: A total of 10 biopsy procedures were performed on 8 patients during the study. The youngest patient was 7 years old. All had successful IENB with tattooing. All biopsies were diagnostic. No procedures were converted to open. There were no technical failures or procedure complications. One patient had a total of 11 biopsies, 6 from the right lung and 5 from the left, performed at 2 separate procedures. Another had 2 biopsies, one from the right lung and one from the left performed at the same operation. In 7 of the 8 patients treatment changes were made based on results of their biopsy.
    Conclusion: Here we present the first described experience of IENB and tattooing of peripheral lung lesions in the pediatric population. We have shown that IENB for peripheral lung lesion localization is a safe and effective technique in pediatric oncology.

    Abstract Background: Neuroblastoma is the most common non-central nervous system (CNS) solid malignant tumor in children. The surgical treatment of high-risk neuroblastoma presents a challenge, and the benefits of aggressive surgical resection have been called into question.
    Objectives: To examine our experience with surgical resection of neuroblastoma.
    Methods: We report on a retrospective chart review of our preliminary surgical experience in 25 patients with neuroblastoma who underwent surgery performed by a single surgeon at two institutions over a 3 year period. Demographic data, including stage of tumor and risk stratification, were recorded. Primary outcome was total gross resection. Patients were followed for 3 years after surgery.
    Results: We found that 80% of the patients, including those with high-risk neuroblastoma tumors, had total gross resection of their tumor with minimal operative morbidity and no mortality; 88% had greater than 90% resection of their tumor. Overall, 3 year survival was 84% (21/25).
    Conclusions: Resection of neuroblastoma, even large, high-risk, bilateral tumors, was possible when performed by surgical teams with considerable experience.

    Abstract Polyorchidism is a rare diagnosis. When recovered, it is frequently found in combination with other urologic pathologies. We report the case of a 14-month-old child with imperforate anus who was found to have polyorchia during repair of his inguinal hernia. Although cryptorchidism is not an uncommon finding in patients with imperforate anus, polyorchidism has never been reported. This is an unusual presentation of a rare entity.

    Abstract Congenital diaphragmatic hernia (CDH) is one of the most common congenital abnormalities. Children born with CDH suffer a number of co-morbidities, the most serious of which is respiratory insufficiency from a combination of alveolar hypoplasia and pulmonary vascular hypertension. All children born with CDH display some degree of pulmonary hypertension, the severity of which has been correlated with mortality. The molecular mechanisms responsible for the development of pulmonary hypertension in CDH remain poorly understood. Angiopoitein-1 (Ang-1), a central mediator in angiogenesis, participates in the vascular development of many tissues, including the lung. Although previous studies have demonstrated that Ang-1 might play an important role in the development of familial pulmonary hypertension, the role of Ang-1 in the development of the pulmonary hypertension associated with CDH is poorly understood. The aim of this study was to examine the role of the Ang-1 pathway in a murine model of CDH. Here, we report that Ang-1 appears important in normal murine lung development, and have established its tissue-level expression and localization patterns at key time-points. Additionally, our data from a nitrofen and bisdiamine-induced murine model of CDH suggests that altered expression patterns of Ang-1, its receptor Tie-2 and one of its transcription factors (epithelium-specific Ets transcription factor 1) might be responsible for development of the pulmonary vasculopathy seen in the setting of CDH.

    Abstract Background/purpose: Congenital diaphragmatic hernia affects approximately 1 in every 2000 live births. The etiology of these diaphragmatic defects is unknown. Using mice with a targeted deletion of fibroblast growth factor 10 (FGF10), which display a complete lack of lung tissue, we have examined the relationship between lung hypoplasia and diaphragmatic development.
    Methods: The diaphragms of FGF10 null mice were examined at 2 embryonic time-points and compared with their heterozygous and wild-type littermates.
    Results: FGF10 null mice had phenotypically normal diaphragms when compared with wild-type littermates at both time-points studied.
    Conclusion: Normal diaphragm development appears to occur independent of lung development in mice.

    Abstract A 6-year-old girl with hereditary multiple exostoses presented with spontaneous hemothorax and pericardial effusion. Chest computed tomographic scan showed left-sided costal exostoses protruding into the left side of the chest. She underwent successful thoracoscopic resection of 3 left rib exostoses and made a full recovery. This report illustrates this rare clinical scenario and reviews the previously published reports of this complication of costal exostoses.

    Abstract Purpose: Risk factors that predispose children with congenital diaphragmatic hernia (CDH) to recurrence remain poorly defined. We report a large series of recurrent CDH and ask whether prenatal patient factors or postnatal treatment variables better predict recurrence.
    Methods: Two hundred thirty-eight neonates with unilateral CDH underwent repair from 1990 to 2006. Data were assessed by chi(2) and Mann-Whitney U tests. Multivariate regression identified independent predictors of recurrence. Statistical significance was set at P < .05.
    Results: We identified 24 recurrences (10%). Median time from repair to recurrence diagnosis was 4.9 months. Patients with recurrence were older (P = .02) and more often required abdominal wall patches at initial repair (P = .01) compared to nonrecurrence patients. Postoperative length of stay (LOS) after initial repair (P < .01) and morbidity (P = .01) were greater in recurrence patients. Use of diaphragm patch at initial repair was greater in patients with recurrence but only approached statistical significance (P = .05). Only 2 variables independently predicted recurrence by multivariate regression as follows: abdominal (not diaphragm) wall patch during initial repair (odds ratio [OR] 3.50; P = .04) and postoperative LOS (OR, 1.012; P = .01).
    Conclusion: Neonates at risk for CDH recurrence are better identified by postnatal treatment variables than by prenatal patient factors. Although age at repair and diaphragm patch use are greater in recurrence patients, the only factors to independently predict recurrence were postoperative LOS and abdominal wall patch use. These data can help optimize follow-up regimens.
